Ènergoèffektivnost èkspluatacii tehničeskih sistem

The paper shows that the low energy efficiency exploitation of technical systems to a large extent determines their negative impact on the environment and humans. On the basis of the energy balance equation shows that the decrease in efficiency due to the loss of energy during its conversion and the transmission and power factor with reduced electrical devices technical systems. Reduced power factor due to the fact that the technical system operation the power consumption of the drive motor on the shaft of these systems much less than its nominal value. Loss of energy and reducing power factor leads to contamination of the environment and reduction of human security in the operation of technical systems. The most effective way to improve the energy efficiency of operation is to improve the power factor by compensating the phase shift, which reduces the current consumption due to compensation of the reactive component of it. Experimental research in machine tool technology systems have shown that the application of the method of compensation of phase shift can significantly improve the energy efficiency of the operation of these systems. This significantly reduces the amount of power consumption, the value of its reactive component and the input current and greatly increasing the power factor of technical systems in their operation.
